Oral Peripheral Mu Opioid Receptor Antagonist
Opioid analgesics such as morphine continue to play a critical role in chronic malignant and non-malignant pain control. Opioid-induced constipation (OIC) is a common and well recognized complication of opioid therapy that has a significant impact on the quality of life of patients. The abdominal discomfort and nausea associated with OIC can be debilitating and may interfere with successful pain management.
TD-1211 is a multivalent inhibitor of the mu opioid receptor that was discovered and developed by Theravance.
We demonstrated preclinically that TD-1211 is orally bioavailable with no evidence of activity in the CNS (in other words, TD-1211 is "peripherally restricted"). TD-1211 is an investigational, once-a-day treatment designed with the goal of alleviating gastrointestinal side effects of opioid therapy without affecting analgesia. The objective of this program is to identify and develop a best-in-class-treatment to restore normal bowel function in patients with OIC.
We have completed a Phase 2b study evaluating TD-1211 in patients experiencing OIC.
